Abstract：

In　this　paper,　we　report　a　new　method　for　preparing　bottlebrush　polymers　(BBPs)　with　a　polyvinyl　ether　(PVE)　backbone　using　a　combination　of　cationic　polymerization　and　atom　transfer　radical　polymerization　(ATRP).　A　Br-functionalized　vinyl　ether　monomer,　2-vinyloxyethyl-2-bromoisobutyrate　(VEBB),　was　synthesized　for　the　“grafting-from”　synthesis　of　BBPs,　and　it　can　readily　undergo　cationic　polymerization　in　the　presence　of　an　organic　Brønsted　acid　and　allow　for　subsequent　ATRP　of　different　monomers　to　introduce　side　chains.　Accordingly,　a　series　of　bottlebrush　polymers　with　a　well-defined　backbone　and　different　side　chains　can　be　prepared　via　this　combination　of　cationic　polymerization　and　ATRP　technology.　The　thermal　transition　of　PVE-based　bottlebrush　polymers　was　studied　by　differential　scanning　calorimetry　(DSC).　The　surface　morphologies　and　aggregation　behaviours　of　these　nanoscopic　single　molecules　were　studied　by　tapping-mode　atomic　force　microscopy　(AFM)　on　mica.　©　2025　The　Royal　Society　of　Chemistry.
